Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a hemorrhoid ligation device which can be recycled. Background Art

[0002] Most medical band ligation devices now work by inserting a small rubber ring into the root of the internal hemorrhoids. The principle of rubber band ligation for treating internal hemorrhoids is to use an instrument to insert a small rubber ring into the root of the hemorrhoids, and use the strong elasticity of the rubber ring to block the blood supply to the internal hemorrhoids, causing the hemorrhoids to ischemia, necrosis, and fall off and heal themselves.

[0003] Most of the hemorrhoid ligation devices are now disposable, and some reusable ligation devices are highly efficiently disinfected. However, after long-term use, the ligation barrel will still have residual bacteria even after efficient disinfection. If it is not thoroughly disinfected, it will be used as usual, causing cross-infection between patients, thus resulting in medical accidents. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a hemorrhoid ligation device which can be recycled.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A reusable hemorrhoid ligation device comprises a gun shell, a fixing head is arranged at the front end of the gun shell, a plurality of wire tubes are clamped on the fixing head, and a ligation gun barrel is installed at the front end of the fixing head;

[0007] The tying gun barrel comprises a connecting part arranged at one end of the tube body, the connecting part tube body is assembled and connected with the fixing head, the other end of the tying gun barrel away from the connecting part tube body is set as a gun head, and a second air extraction channel is opened through the tying gun barrel tube body.

[0008] In addition, the preferred structure is that a plurality of fixing seats are evenly arranged on the surface of the cylinder with a larger diameter of the fixed head, a threaded portion is opened on the surface of the cylinder with a smaller diameter of the fixed head, and a plurality of O-rings are sleeved on the surface of the cylinder with a smaller diameter of the fixed head and away from the threaded portion.

[0009] In addition, a preferred structure is that a wire tube is clamped on each of the fixed clamping seats, an elastic loop rope is provided on the wire tube, and the head of the elastic loop rope away from the fixed head can be sleeved on the gun head.

[0010] In addition, a preferred structure is that a first air extraction channel is opened on the fixed head, and the diameter of the first air extraction channel is consistent with that of the second air extraction channel.

[0011] In addition, the preferred structure is that a plurality of protrusions are evenly arranged on the outer wall of the connecting part tube body, a threaded hole is opened in the connecting part tube body, the threaded hole is connected to the second air exhaust channel, the threaded hole and the threaded part of the fixed head are clearance-matched, and a sealing gasket is attached to the bottom wall of the threaded hole.

[0012] In addition, a preferred structure is that a plurality of grooves are evenly formed on the outer wall of the gun head tube, and the rope loop at the head of the elastic rope is sleeved in the groove.

[0013] The beneficial effects of the utility model are as follows: by setting the ligation gun barrel to be installable, the assembly connection can be completed by only screwing the tube body of the connecting part onto the fixed head, so that after the ligation operation is completed, in order to recycle the hemorrhoid ligation device, it is only necessary to screw the ligation gun barrel off the fixed head, and then discard the used ligation gun barrel, while the gun shell part with higher cost does not need to be discarded, and only needs to be disinfected for recycling, and a new ligation gun barrel can be assembled, which effectively reduces the cost and ensures that the ligation gun barrel will not be used multiple times to cause cross infection.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A reusable hemorrhoid ligation device comprises a gun shell 1, a fixed head 2 is arranged at the front end of the gun shell 1, a plurality of wire tubes 4 are clamped on the fixed head 2, and a ligation gun barrel 3 is installed at the front end of the fixed head 2;

[0022] The tying gun barrel 3 includes a connecting portion 31 arranged at one end of the tube body, the connecting portion 31 tube body is assembled and connected with the fixed head 2, and the other end of the tying gun barrel 3 away from the connecting portion 31 tube body is set as a gun head 32, and a second exhaust channel 33 is opened through the tube body of the tying gun barrel 3.

[0023] Among them, a plurality of fixed sockets 22 are evenly arranged on the surface of the cylinder with a larger diameter of the fixed head 2, a threaded portion 21 is opened on the surface of the cylinder with a smaller diameter of the fixed head 2, and a plurality of O-rings 23 are sleeved on the surface of the cylinder with a smaller diameter of the fixed head 2 and away from the threaded portion 21. The O-rings 23 can improve the sealing performance of the connection of the fixed head 2.

[0024] In addition, each fixed base 22 is provided with a wire tube 4, and an elastic loop rope 5 is provided on the wire tube 4. The head of the elastic loop rope 5 away from the fixed head 2 can be sleeved on the gun head 32. By providing multiple wire tubes 4, it is possible to perform ligation on multiple hemorrhoids at one time.

[0025] Moreover, a first air extraction channel 24 is provided on the fixing head 2 , and the diameters of the first air extraction channel 24 and the second air extraction channel 33 are consistent.

[0026] At the same time, a plurality of protrusions 311 are evenly arranged on the outer wall of the tube body of the connecting part 31, and a threaded hole 313 is opened in the tube body of the connecting part 31. The threaded hole 313 is connected to the second air exhaust channel 33, and the threaded hole 313 is clearance-matched with the threaded part 21 of the fixed head 2. A sealing gasket 312 is attached to the bottom wall of the threaded hole 313. The threaded hole 313 facilitates the fixing head 2 to be screwed in for assembly, connection and installation.

[0027] Moreover, a plurality of grooves 321 are evenly formed on the outer wall of the gun head 32 , and the head loops of the elastic loop 5 are sleeved in the grooves 321 . The grooves 321 are convenient for sleeved with a plurality of elastic loops 5 .

[0028] In this embodiment, the device can be used when a hemorrhoid ligation device is used for ligation surgery. First, a new ligation gun barrel 3 is connected to the gun housing 1, and the fixing head 2 is screwed into the tube body of the connecting part 31. The threaded part 21 and the threaded hole 313 are clearance-matched, so that the fixing head 2 and the connecting part 31 can be assembled and connected.

[0029] At this time, the ligation operation can be performed. The gun head 32 is aimed at the hemorrhoidal tissue and then suction is performed. Suction is performed through the first suction channel 24 and the second suction channel 33. After all the hemorrhoidal tissue is sucked into the gun head 32, the elastic rope 5 on the front side is used for ligation first, and the wire tube 4 that fixes it is removed from the fixed base 22 where it was originally clamped, and then the elastic rope 5 is detached from the groove 321 of the gun head 32, and then the ligation work is performed. When it is necessary to ligate hemorrhoidal tissue in other parts in the future, the same method is used to ligate the remaining elastic ropes 5 in turn.

[0030] After the ligation operation, in order to recycle the hemorrhoid ligation device, it is only necessary to unscrew the ligation gun barrel 3 from the fixed head 2, and then discard the used ligation gun barrel 3. The gun shell 1, which is more expensive, does not need to be discarded, but only needs to be disinfected for recycling, and a new ligation gun barrel 3 can be assembled.

[0031] Furthermore, when the fixing head 2 is assembled and connected with the pipe body of the connecting portion 31 , the O-ring 23 and the sealing gasket 312 can effectively improve the air tightness of the assembled connection to prevent air leakage.

[0032] In the utility model, by setting the ligation gun barrel 3 as an installable type, the assembly connection can be completed only by screwing the tube body of the connecting portion 31 onto the fixed head 2, so that after the ligation operation is completed, in order to recycle the hemorrhoid ligation device, it is only necessary to unscrew the ligation gun barrel 3 from the fixed head 2, and then discard the used ligation gun barrel 3, and the more expensive gun shell 1 part does not need to be discarded, and only needs to be disinfected for recycling, and a new ligation gun barrel 3 can be assembled, which effectively reduces the cost and ensures that the ligation gun barrel 3 will not be used multiple times to cause cross infection.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
